Linguists believe PIE had two root words for water: *ap- and *wed-. The first (preserved in Sanskrit apah) was "animate," referring to water as a living force; the latter referred to it as an inanimate substance. The same probably was true of fire (n.).

(wô'tər) A colorless, odorless compound of hydrogen and oxygen. Water covers about three-quarters of the Earth's surface in solid form (ice) and liquid form, and is prevalent in the lower atmosphere in its gaseous form, water vapor. Water is an unusually good solvent for a large variety of substances, and is an essential component of all organisms, being necessary for most biological processes. Unlike most substances, water is less dense as ice than in liquid form; thus, ice floats on liquid water. Water freezes at 0°C (32°F) and boils at 100°C (212°F). Chemical formula:H2O.
